使用springboot整合jsp，在后端写入公交路线名称和详细站点，前端页面可条件查询具体的内容，如公交路线，公交名称，车俩信息等。
前台用户端：
BusData.txt
pom.xml加入jsp模板引擎支持：
<dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency>
springboot配置jsp
spring.mvc.view.prefix=/ spring.mvc.view.suffix=.jsp
bus数据初始化
@PostConstruct
private void initBusData(){
try{
File file = new File(BusMap.getClass().getResource("/").getPath());
FileReader fileReader = new FileReader(file.getPath()+"/static/BusData.txt","GBK"); //初始化BusData.txt 数据
List<String> readLines = fileReader.readLines();
for(String str:readLines){
if(!"".equals(str)){
String[] data=str.split("#");
String way=data[0]; //几路线
String location=data[1];/ /地名
String[] locations=location.split(",");
List<Bus> list=new ArrayList<>();
for(int i=0;i<locations.length;i++){
int busnum=0;
if(i%4==0){ //随机busnum
busnum=1;
}if(i%5==0){
busnum=2;
}
Bus bus=new Bus(locations[i],busnum);
list.add(bus);
}
WayList.add(way); //添加路线
BusMap.put(way,list); //添加车站
}
}
}catch (Exception e){
e.printStackTrace();
}
}
路线查询
@RequestMapping("/way")
public String search(HttpServletRequest request,String way) {
try {
if(null==way||"".equalsIgnoreCase(way)){
request.setAttribute("list", BusMap.WayList); //没有搜索默认显示所有路线
return "way";
}else{
List<String> wayList=new ArrayList<>();
//模糊查询路线
for(String str:BusMap.WayList){
if(str.indexOf(way)>-1){
wayList.add(str);
}
}
if(wayList.size()>0){
request.setAttribute("list", wayList); //模糊搜索出来的路线列表
return "way";
}else{
return "noView"; //没有所选路线
}
}
} catch (Exception e) {
e.printStackTrace();
}
return "way";
}
公交车路线站展示
@RequestMapping("/view")
public String view(HttpServletRequest request,String way) {
try {
List<Bus> list= BusMap.getBusMap(way);
if(list.size()>0){
request.setAttribute("list",list ); //获取总路线
request.setAttribute("firstBus", list.get(0).getLocation()); //第一站
request.setAttribute("lastBus", list.get(list.size()-1).getLocation()); //最后一站
int size = list.size();
size =(size-1)*99;
request.setAttribute("size",size);
return "view";
}
} catch (Exception e) {
e.printStackTrace();
}
return "noView";//没有对应公交车站
}
//前端页面数据渲染
<div class="pageContent" style="background: #eeeeee;">
<div class="pageFormContent" layoutH="55">
<div class="timeText">${firstBus}<----->${lastBus}
